IRS2153DSPBF

Gate Driver Overview

The IRS2153DSPBF is a self-oscillating half-bridge gate driver IC from Infineon Technologies, manufactured on an advanced silicon platform. It integrates high-side and low-side drivers in an SOIC-8 surface-mount package. The device supports a supply voltage range of 10.1 V to 16.8 V with a typical operating current of 5 mA. It delivers a peak output current of 260 mA, featuring rise and fall times of 120 ns and 50 ns respectively. Maximum delay times are capped at 350 ns for both turn-on and turn-off states. Power dissipation is rated at 625 mW, and it operates within a temperature range of -40°C to +125°C.

Gate Driver Feature Summary

• Self-oscillating architecture eliminates the need for external timing components
• Integrated high-side and low-side driver channels for half-bridge configurations
• CMOS logic interface compatible with standard digital control signals

Gate Driver Applications

• Induction heating power supplies
• Switched-mode power supply (SMPS) topologies
• Motor drive applications requiring half-bridge control

Gate Driver Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and check for end-of-life notifications, as this part may be subject to obsolescence. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering. Validate that the SOIC-8 footprint matches your PCB design specifications before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a self-oscillating solution is required to simplify circuit design by removing external oscillators. The SOIC-8 package suits space-constrained surface-mount applications. Consider the 260 mA output current capability against load requirements. Verify that the 10.1 V minimum supply voltage aligns with your system's power rail availability and that the 600V blocking capability meets insulation requirements.

Gate Driver Part Context

This part belongs to the IRS2153 family, which includes variants like the IRS2153DSTRPBF and IRS21531DSPBF. These devices share the same core self-oscillating half-bridge functionality but differ in packaging options such as tape-and-reel versus tube. The DSPBF suffix indicates a specific lead-free and halogen-free compliant variant within the broader IR2153 lineage.

Gate Driver Replacement Considerations

The IR2153PBF serves as a legacy through-hole alternative, though it differs in package type and output current characteristics. For direct functional substitution in surface-mount designs, verify compatibility with the IRS2153DSTRPBF or IRS21531DSTRPBF, ensuring pinout and electrical parameters match your existing design constraints.
